Key Document


The PMP40144 is a 12V 2A reference design solution for PoE applications. The solution implements a high efficiency primary side controller UCC28704, eliminating feedback components(TL431, opto-coupler). The efficiency is >89% at full load. Integrated input UVLO, OVP and output OVP, OCP improves the power system reliability. The design is achieved in a compact form factor (68mm X 36mm X 15mm).

  • >89% full load efficiency
  • Primary side regulation (PSR) eliminates opto-coupler
  • Input UVLO, OVP, output OVP
  • Output overcurrent protection with automatic retry
  • Size L*W*H 68mm*36mm*15mm
